Make sure the ignition switch is turned to LOCK (0), then jump the SCS line with the HDS. 2. Remove the cover (A). 3. Lift up the under-hood fuse/relay box (D). 4. Remove the coolant reservoir (E). Disconnect ECM/ PCM connectors A, B, and C, and probe the NOTE: ECM/PCM connectors A, B, and C have , B= , C= ) embosed on them for identification. 5. When diagnosis/troubleshooting is done at the ECM/PCM connector, use the terminal test port (A) 6. Connect one side of the patch cord’s terminals (A) to a commercially available digital multimeter (B), 7. Gently contact the pin probe (male) at the terminal test port from the terminal side. Do not force the • For accurate results, always use the pin probe (male). • To prevent damage to the connector terminals, do not insert test equipment • Do not puncture the insulation on a wire. Punctures can cause poor or intermittent 08/08/21 14:12:34 61SNR030_110_0006 |
